Rear Chassis Brace XL for TRX-4 v1

(1 review) Write a Review
Carbon fiber-reinforced nylon

Our rear chassis brace has a narrower crossmember than the stock brace, making more room for long battery packs or flat load floors when used together with our Low CG Battery Tray. The XL version fits packs up to 158mm long and is printed in-house using carbon fiber-reinforced nylon.

For even higher print resolution and smoother surface texture, SLS nylon prints are available through our Shapeways store:

    Rear Chassis Brace XL for TRX-4 v1

    Posted by Brian Brigg on Sep 5th 2018

    I consider this as a must have when using the low CG battery tray as the battery packs are moved lightly rearward by the shape that the tray has to be. Finish is at the better end for 3D printed parts in my experience.

    Installation is easy with only one side of the rear battery tray screws needing to be removed along with one side of the rear bumper mount in order to allow the frame rails to flex apart enough for the old brace to be removed and this one to slide in. The holes line up perfectly and the stock screws fit firmly.
